Looking to fit a sump under my stand that is no longer than 24" and less than 16" deep. Might consider a DIY/custom but looking for the best layout that one can fit using 24".
What are you looking to use it for?
You could do a DIY 10 gallon tank. That would put you at about 20x10 footprint.
I have a used cube that I am looking to sell.
I had posted it in the classifieds for $ 100 shipped.
